Spiceworks only detects these antivirus packages. If you're having trouble with antivirus detection please see if your software is in the list.

Note that you only need 1 installation of Spiceworks. Spiceworks is browser-based and can be accessed by navigating to http://server-name:port where server-name is the name of the machine where Spiceworks is installed and port is the port number (it can be left off if Spiceworks is running on port 80).
